The light-emitting diode is used as a light-emitting source, and a non-circular light-shaped light-emitting device can be produced. [Prior Art] Early, for example, vehicle lights are usually designed to use the concentrating effect of the 'mirror or front lamp cover on the inner side of the lamp holder to enable the light source of the bulb to be concentrated in a predetermined direction. The lamp for the illuminating source has been replaced by the illuminating diode (LED) in recent years because of the high power consumption. . . . . . . . . . , the following only one of the LEDs is used. Explain the rear fog lamp of the car for the light source. Referring to Figures 1, 2, and 3, the conventional light-emitting device 1 comprises: a lamp housing ^' and a group of light-emitting units 12 mounted in a housing of the lamp housing n, the lamp housing 11 having a light-emitting unit 12 disposed therein. a lamp holder ill, and a lamp cover 112 that is disposed in front of the lamp holder 111, and the light-emitting unit 12 has a circuit board 121 and two rows of light-emitting diodes 122 mounted on the circuit board 121 in a row. The distance between the adjacent light-emitting diodes 22 is about 0.8 cm, and each of the light-emitting diodes U2 has a circular light-emitting portion 123 located at the center and capable of generating an approximately circular source. When the conventional light-emitting device 1 is in use, the light generated by the light-emitting diode 122 is projected by the circular light-emitting portion 123 through the lamp cover 112 onto a test screen of a fixed distance (for example, 3-16 m), although the light-emitting diodes 122 are It is arranged in two rows, but since the distance between each other (〇·8 cm) is small relative to the projection distance (3·16πι), these light-emitting diodes 122 are projected to a fixed point, for example, as shown in Fig. 3 200836951.. ..... - . . . . 乂- . . . . - :.:V : L . - . Approximate circular symmetrical light shape. The circular light shape of the light intensity of the up, down, left, and right relative positions is almost the same, although it has the function of illumination and warning, the general specification of the light distribution value of the vehicle lamp requires that the horizontal width should be greater than the vertical direction. For example, in the ECE (Ec〇n〇mic Commission of Europe) Regulation R-38, the light distribution value of the rear fog lamp is taken as an example. The light distribution value of the specification is roughly in the shape of a diamond. • In the area, the light intensity value of each point in the diamond area must be between 75~3〇〇cd (candlelight), and the light intensity value of each point on the horizontal line H line at 10L~10R must be between 150 ~300cd, and the light intensity value of each point on the su-5〇 in the vertical direction V line must also be between 150~30〇Cd, that is, the horizontal direction line in the diamond specification interval is wider than the vertical direction v line. ° Further, the conventional light-emitting device 1 having the light-emitting diode 122 is used. When the lower-power LED 220 is used, the approximately circular shape of the light is easily satisfied by the vertical V-line light intensity specification, but The regulations on the horizontal Η line in the regulation cannot be met. Conversely, when the higher power luminescence _ diode 122 is used, although the specification of the light intensity on the line 11 in the horizontal direction can be satisfied, it is wasteful in the vertical direction. That is, although the general regulation stipulates that the vertical direction region is smaller than the horizontal direction in the specification of the light distribution value of the vehicle lamp, the light shape generated by the light-emitting diode 122 having the circular light-emitting portion 123 is circular, but In order to enhance the light intensity of the adjacent edge of the horizontal line, it is necessary to use a larger power LED 220. This design not only has a large power consumption, but also requires a large amount of light. Two jujube plates 122, resulting in poor spatial design flexibility, and high manufacturing costs, etc. 200836951 - · - · .

The beneficial effect of the invention is that: by the design that the horizontal axis length of the first light-emitting diode is greater than the vertical axis length, the light-emitting device can generate a light shape having a width greater than a south degree, and the light-emitting portion of the second light-emitting diode is used. The design of the horizontal axis length equal to or less than the vertical axis length can complement the lack of light intensity above and below the central portion, so that the illuminating device can conform to the lamp with less and less power illuminating the vertical body. For the regulation of the light distribution value. The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention.

That is, the light-emitting portions 321 ® of the first light-emitting diodes 32 of the present embodiment are all horizontally elliptical, and the light-emitting portions 331 of the second light-emitting diodes 33 are all straight ellipsoids. Referring to FIGS. 5 and 7, in the light-emitting device of the present embodiment, the light-emitting portion 321 having a horizontal ellipsoid-circle can generate a light shape having a side width but a small height, and the light-emitting portions 331 of the straight elliptical shape can be generated.

Therefore, because of the integration of the two types of light bodies 32, 33, which are in accordance with the regulations of the national time lamp, the design is based on different light shapes. The combination of the illuminating two is 4'. Therefore, in the design, the low-power 32' 33 ^ body design is used in this embodiment, as long as the light-emitting diodes 32, 33 are less than the conventional ones, and all of them are complemented. The required light distribution value is required in different directions. Therefore, in addition to having (4) energy and saving disproportionation, the embodiment of the present invention can also reduce the design space of the illuminating device, and at the same time make the lamp design more flexible in shape design. Referring to FIGS. 8 and 9, a second preferred embodiment of the light-emitting device of the present invention also includes a circuit substrate 31, eight first light-emitting diodes 32, and four second light-emitting diodes 33, wherein the first The position and shape of the light-emitting diode 32 are the same as those of the first embodiment, and the second light-emitting diodes have a light-emitting portion 33 in the center, and the light-emitting portion 33 is circular.
